CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. patent application Ser. No.14/839,339, filed Aug. 28, 2015, which claims the benefit of U.S.Provisional Application No. 62/095,539, filed Dec. 22, 2014. The entiredisclosures of both are incorporated herein by reference.

BACKGROUND

Media consumption devices, such as smartphones, tablets, and smarttelevisions (TVs), can access digital content and receive data, such asstreaming media, from data networks (such as the Internet). Streamingmedia refers to a service in which media content can be provided to anend user (upon request) over a telephone line, a cable, the Internet,and so forth. For example, a user can view a movie without having toleave their residence by requesting the movie via a media consumptiondevice and viewing the movie as it is streamed over the Internet. Inanother example, users can access various types of educational content,such as video lectures, without having to physically attend a school oreducational institution.

As the number of media consumption devices continues to increase, mediacontent generation and delivery may similarly increase. With an increasein use of media consuming devices to access streaming media, content ornetwork providers can distribute contextually-relevant material toviewers that are consuming streaming media. For example, localbroadcasters can integrate contextually-relevant advertisements andinteractive content with streaming media.

DESCRIPTION OF EMBODIMENTS

To provide viewers with media content, a media content provider maydecide to stream the media content to viewers, such as by delivering themedia content over the Internet to the viewers. The media contentprovider can be an individual or an organization such as a localbroadcaster, a multi-channel network provider, or another content owneror distributor. The media content may be content (such as video data)originating from one or more live broadcast media feeds. For example, amedia content provider may provide a user media content via a linearmedia channel (e.g. media provided from a live media feed source to aviewer) over the Internet.

The word “content” can be used to refer to media or multimedia. The word“content” can also be a specific term that means the subject matter ofthe medium rather than the medium itself. Likewise, the word “media” andsome compound words that include “media” (e.g. multimedia, hypermedia)are instead referring to content, rather than to the channel throughwhich the information is delivered to the end user or audience. Anexample of a type of content commonly referred to as a type of media isa “motion picture” referred to as “a film.”

Streaming media can be media content that is received by and presentedto an end-user from a content provider over a network. Streaming mediacan be a playback or live media that can be played on media consumptiondevices. When media is played back on the media consumption devices, themedia content may be stored on a server for a period of time and thensent to the media consumption devices over the network upon request,e.g., a video on demand (VOD) service. Live streaming can be thestreaming of a live or real-time event, such as a news event or sportsevent, to the media consumption devices as the event is occurring.

Streaming or transferring media content to media consumption devicesover networks can include encoding data (such as video and/or audiodata) and/or the transmission of the data over networks. In one example,data can be encoded to provide a secure transfer of data between aprovider and a media consumption device. In another example, data can beencoded or converted to adjust for varying display sizes, processingcapabilities, network conditions, and/or battery capabilities of themedia consumption device. The content generation, processing, encoding,and/or distribution can be performed by a provider (such as at a server)and processing, decoding, and/or content displaying can be performed atthe media consumption devices.

Additionally, while advertising can be an engaging venue to advertiseproducts or services, traditional media consumption advertising lackstargeted and personalized advertising. Traditional media consumptionadvertising also lacks a return path for users to engage with anadvertisement and/or enable retargeting of the users once anadvertisement has been viewed by the users. To increase an impact andeffectiveness of the advertisement, an advertiser may be interested intargeting particular advertisements to particular sets of viewers, suchas a viewer of a selected demographic or location. The advertiser may beinterested in interacting with the targeted viewer when the targetedviewer sees the targeted advertisement. For example, a content providermay generate a content feed advertisement link to the media content thatis relevant to a particular media item. Where consumers of the mediaitems generally tend to select media items that are interesting to them,linking advertisements to media content can enable advertisers to directtheir advertisements to consumers who are interested in a particulartopic. Media consumption devices with automatic content recognition(ACR) devices or media consumption devices that receive content withcontextually-relevant material can provide viewers with targeted and/orpersonalized advertising as well as an interactive viewing experience.

In one embodiment, ACR devices can use digital watermarking for ACR ofbroadcast digital content. For example, broadcast content can bepreprocessed (e.g. processed prior to broadcast) to insert watermarkdata within a content signal. That watermark data can be detected by asmart TV or an ACR device to enable identification and synchronizationof the media content with the broadcast content.

In another embodiment, an ACR device can identify audio and/or videocontent using content fingerprinting. Content fingerprinting can be aprocessing device that identifies, extracts, and compresses fingerprintcomponents of a media content to uniquely identify the media content byits “fingerprint.” In one example, fingerprint components can be visualvideo features such as key frame analysis, colors, and motion changesduring a video sequence. The ACR device can identify the video contentas the video content may be displayed on a media consumption device bymatching a sequence of content fingerprints for the video content beingdisplayed with a database of content fingerprints. An advantage ofcontent fingerprinting can be to process the media content while mediacontent is being broadcasted or streamed (e.g., live processing) orwithin a selected threshold period of time after the media content isbroadcast or streamed (e.g. substantially live processing). As the ACRdevice processes the media content, the ACR device can adjust for userbehavior while the user may be viewing the media content (e.g. live orsubstantially live adjusting). In one example, the user behavior can bechanging or pausing a channel, adjusting a volume of the mediaconsumption device, changing menu settings, and so forth. In anotherexample, the user behavior can be viewing time-shifted content.

For live streaming, multiple devices and/or complex infrastructure canbe used to provide a content feed with the contextually-relevantmaterial. For example, traditionally, media content can be encoded by anencoder before providing the media content to a media consumptiondevice. A provider, such as a broadcaster, providing media content to aviewer may desire to distribute contextually-relevant material(including advertisements and interactive content) to viewers.Traditionally, when the provider requests that the media content includecontextually-relevant material, the encoder can provide the mediacontent to an ACR fingerprinter. The ACR fingerprinter can insertcontextually-relevant material into the encoded media content and themedia content can be provided to the viewer with contextually-relevantmaterial.

As multiple devices are used for the preparation and delivery of mediacontent with contextually-relevant material, infrastructure complexity,resource support, and system setup time and complexity can increase. Forexample, traditionally, ACR service vendors can provide a broadcasterwith ACR fingerprinting services and/or a device that performs ACRfingerprinting. Similarly, content encoding and uploading servicevendors can provide encoding and uploading services to delivering videostreams over the Internet. For example, content encoding and uploadingservice vendors can provide devices or software for installation onapplications that perform content stream preparation and delivery.However, the traditional separate ACR fingerprinting services and thecontent encoding and uploading services can cause a system of a contentprovider to experience faults in providing content to streaming contentviewers.

Aspects of the present disclosure address the above noted deficiency ofusing a content device to provide media content using a linear channel.The ACR device can simultaneously fingerprint media content and encodeand upload the media content to a server, such as a cloud server, toprovide the media content to the media consumption device. The mediacontent can provide a viewer of the media consumption device withencoded media content including contextually-relevant material. In oneembodiment, the linear channel can be created using a cloud computingsystem.

FIG. 1 illustrates a content preparation system 100 to prepare mediacontent according to one embodiment. The content preparation system 100can include a content device 102, an ACR cloud(s) or server(s) 110, anda broadcast server or cloud(s) 112. The ACR cloud(s) 110 and/or thebroadcast cloud(s) 112 can be cloud-based servers. The content device102 can include a housing with a processing device disposed on a circuitboard within the housing. The content device 102 can include a capturedaemon 104, a capture interface 106 coupled to the processing device,and/or a software updater 108. The content device 102 can receive mediacontent from a content feed 124 and prepare the media content to includecontextually-relevant material that can be delivered to a mediaconsumption device.

The content device 102 can receive the content feed 124 using a captureinterface 106. The capture interface 106 can be used to capture andconvert media content from the content feed 124. The media content caninclude audio content, video content, or a combination thereof. In oneexample, the content feed 124 is a high definition (HD) serial digitalinterface (SDI) stream. In another example, the content feed 124 is astandard definition (SD) SDI stream. In one example, the captureinterface 106 can receive a content feed using a data port. In oneexample, the data port can be a coaxial cable port, such as a BayonetNeill-Concelman (BNC) port. In another example, the data port can be ahigh definition multimedia interface (HDMI) port. In another example,the capture interface 106 is a capture card. In this example, thecapture card includes the data port that is an internet protocol (IP)network interface. The IP network interface can be an Ethernet RJ45 portthat receives the media content contained in an MPEG-2 Transport Stream.In another example, the content device 102 is processing logic thatexecutes as a process on a remote server and receives media content viaa software application programming interface (API). The processing logicmay include hardware (e.g., circuitry, dedicated logic, programmablelogic, microcode, etc.), software (e.g., instructions executed by aprocessing device), firmware or a combination thereof. The may beperformed by processing logic of the content preparation system 100.

The capture interface 106 can include serial digital interface (SDI)ports, e.g., SDI In/Out ports. The SDI ports can be configured toreceive content (e.g., an input port configuration) or send content(e.g., an output port configuration). The capture interface 106 canreceive one or more content feeds using the SDI ports 126-130. When thecapture interface 106 receives multiple content feeds 124, each contentfeed 124 can be fingerprinted, encoded, and/or uploaded, as discussed inthe proceeding paragraphs. For example, the capture interface 106 canreceive 2 content feeds using SDI port 126 and SDI port 128. In thisexample, the capture daemon 104 can process the content feeds 124 inparallel.

When the capture interface 106 receives content from the content feed124, the capture interface 106 can send the content feed 124 to acapturer 114. The capturer 114 can be software, firmware, or hardwarethat can control and/or interact with the capture interface 106. In oneexample, the capturer 114 instructs the capture interface 106 to use oneor more of the SDI ports 126-130 as an input port or output port. Inanother example, the capturer 114 instructs the capture interface 106how to obtain incoming media content, such as audio/video data, based oncapture criteria. In one example, the capturer 114 communicates with thecapturer interface 106 to determine when media content is received fromthe content feed 124. In this example, when media content is received,the capturer 114 analyzes the media content to determine feedproperties. In one example, the feed properties are an audio format anda video format of the media content. In another example, the feedproperties are bitrates of the audio and video content of the mediacontent. The capturer 114 can use the capture interface 106 to obtainadvanced media content information and perform advanced functions, suchas: closed caption information; time codes delivered within the feed;and adjust media content data, such as color space conversion and/orscaling.

When the capturer 114 receives the media content from the captureinterface 106, the capturer 114 can provide the media content to boththe ACR fingerprinter 122 and to the segment encoder 116. For example,the capturer 114 can provide audio/video data to both the ACRfingerprinter 122 and the segment encoder 116 by splitting theaudio/video data for delivery to the ACR fingerprinter 122 and thesegment encoder 116. In one example, the capturer 114 can communicatewith the broadcast server or cloud(s) 112 to indicate when media contentis being received via the capture interface 106 for uploading to thebroadcast cloud(s) 112, e.g., a streaming status. In another example,the capturer 114 can receive a status message from the broadcastcloud(s) 112 indicating a status of the broadcast cloud(s) 112 toreceive streaming content from the capture daemon 104, e.g., a receivingstatus. In one embodiment, the capture daemon 104 can communicate withthe broadcast cloud(s) 112 using a polling method. In this embodiment,the capture daemon 104 can send a status message to notify the broadcastcloud(s) 112 of a streaming status of the capture daemon 104 (such ascontent ready for streaming status or no current content for streamingstatus) and/or retrieve a receiving status from the broadcast cloud(s)112. In another example, the capturer 114 can provide system metricinformation to the broadcast cloud(s) 112, such as central processingunit (CPU) utilization, memory utilization, drive utilization, operatingtemperature, and so forth. In another example, the software updater 108can be configured to update the content device 102. For example, thesoftware updater 108 can use a polling method to communicate with thebroadcast cloud(s) 112 to determine when an update has been scheduled,such as a time of day, and update the content device 102 at thescheduled time.

The segment encoder 116 can receive content from the capturer 114 andencode the content to provide secure content for a transferring of databetween the broadcast cloud(s) 112 and the media consumption device. Thesegment encoder 116 can also encode or convert the data to adjust forvarying display sizes, processing capabilities, network conditions,and/or battery capabilities of the media consumption device.

The segment encoder 116 can encode and write content segments to a diskor a memory of the segment encoder 116. When the content segments havebeen encoded, the segment encoder 116 can then communicate encodedcontent segments to the uploader 118. After the content is communicatedto the uploader 118, the content segments can be deleted from the diskor the memory of the segment encoder 116. When the uploader 118 receivesthe encoded content segments, the uploader 118 can upload the encodedcontent segments to the broadcast cloud(s) 112. When the uploader 118has uploaded the encoded content segments, the uploader 118 can notifythe broadcast cloud(s) 112 that the encoded content segments have beenencoded and can provide content metadata, such as a time the content wascaptured by the capture interface 106 and/or a duration of the content.

The broadcast cloud(s) 112 can process the uploaded encoded contentsegments before delivering the content segments for playback at a mediaconsumption device. The processing by the broadcast cloud(s) 112 caninclude transcoding the content segments into multiple bit rates tosupport adaptive bit rate playback and uploading all resultant segmentsto a content delivery network (CDN).

In parallel with communicating the content to the segment encoder 116,the capturer 114 can generate content frames 120 and can communicate thecontent frames 120 to an ACR fingerprinter 122. In one example, thecontent frames 120 can be audio data. In another example, the contentframes 120 can be video content. In this example, video content can beraw video frames. When the ACR fingerprinter 122 receives the contentframes 120, the ACR fingerprinter 122 can determine how to processand/or transform the content frames 120, such as the raw video frames.

In one example, the content frames 120 can be fingerprintedindividually. In another example, the content frames 120 can befingerprinted in collections or sequences. The ACR fingerprinter 122 candetermine when to fingerprint the content frames 120 individually orsequentially based on an ACR algorithm used by the ACR fingerprinter122. In another example, the ACR fingerprinter 122 can fingerprint thecontent frames 120 differently for different broadcasters or users. Inthis example, the ACR fingerprinter 122 can include different ACRfingerprinting algorithms for different ACR vendors. In one embodiment,the different ACR fingerprinting algorithms can be predetermined andstored on a memory of the ACR fingerprinter 122. In another embodiment,the different ACR fingerprinting algorithms can be provided by thirdparty ACR vendors. When different ACR fingerprinting algorithms may beprovided by the third party ACR vendors, the ACR fingerprinter 122 canaggregate the different ACR fingerprinting algorithms. In one example,ACR fingerprinting can use raw video with in the YUV 4:2:2 colorspaceand at high resolutions. When content feed 124 is received at thecapture interface 106, the capturer 114 can convert the content feed 124to a YUV 4:2:0 colorspace and scale it down in resolution to a thresholdresolution level for encoding by the segment encoder 116. In anotherexample, the ACR fingerprinter 122 can determine information for a firstmedia consumption device using a first ACR algorithm and determine ACRfingerprint information for a second media consumption device using asecond ACR algorithm.

When the ACR fingerprinter 122 has fingerprinted the content frames 120,the ACR fingerprinter can send fingerprints (including channelinformation, time codes, and fingerprint information) to the ACRcloud(s) 110. In one example, the different ACR fingerprintingalgorithms can be used on the same content frames 120 to providedifferent fingerprinter information to ACR cloud(s) 110 of different ACRvendors. Different ACR fingerprinting formats can be used by differentmedia consumption devices manufactured by different contract equipmentmanufacturers (CEMs). An advantage of the ACR fingerprinter 122including ACR fingerprinting algorithms for different ACR vendors can beto enable content to be fingerprinted and provided to viewers viadifferent media consumption devices regardless of the manufacturer ofthe media consumption device. An advantage of fingerprinting the samecontent frames 120 with the different ACR fingerprinting algorithms canbe to provide contextually-relevant advertisements and interactivecontent to viewers with media consumption devices using different ACRfingerprinting. In another example, the content frames 120 can includemedia content from different content feeds. In this example, thedifferent ACR fingerprinting algorithms can be used on the contentframes 120 of the different content feeds to provide differentfingerprinting information to ACR cloud(s) 110 of different ACR vendors.

The different fingerprinting information can be uploaded to ACR cloud(s)110 of the different ACR vendors, respectively. In one example, the ACRcloud(s) 110 can use the ACR fingerprinting information for digitaladvertisement replacement (DAR). In another example, the ACRfingerprinting information can be used for advertisement or contentaugmentation and data collection. The ACR cloud(s) 110 can use thefingerprinting information to match the encoded content withcontextually-relevant advertisements and interactive content. Thematched encoded content and contextually-relevant advertisements andinteractive content can then be provided to the media consumptiondevices for display. In another example, information about the matchingevents can be communicated to the broadcast cloud(s) 112 for analysis ofcontent matching.

In one example, ACR fingerprinting information can be delivered to theACR cloud(s) 110 before broadcast schedule metadata can be communicatedfrom the broadcast cloud(s) 112 to the ACR cloud(s) 110. In anotherexample, the broadcast schedule metadata can be uploaded to the ACRcloud(s) 110 when an entire segment has been encoded and received at thebroadcast cloud(s) 112. In another example, content can be continuouslyfingerprinted and resultant fingerprinting information can becontinuously communicated or communicated at select rates to ACR vendorclouds. The selected rates can be based on the different ACR vendors.For example, one vendor can deliver ACR fingerprinting informationseveral times per second, whereas another vendor may deliver thisinformation once every 2-5 seconds.

In one example, the content device 102 can encoded, encrypt, and uploadcontent to the broadcast cloud(s) 112. In another example, the contentdevice 102 can receive broadcaster-specific schedule metadata from abroadcaster (data about what shows and ads are in the content feedreceived at the capture interface 106). The metadata can be communicatedby the content device 102 to the broadcast cloud(s) 112. In anotherexample, the broadcast cloud(s) 112 can communicate metadata (such asbroadcaster-specific schedule metadata) to the ACR cloud(s) 110 or todifferent ACR cloud(s) 110 of different vendors so that vendors can usthe metadata to match up to the fingerprint information received fromthe ACR fingerprinter 122.

In one example, the content device 102 can use a first communicationchannel to communicate with the broadcast server 112 and use a secondcommunication channel to communicate with an ACR cloud 110. For example,the uploader 118 of the content device 102 can communicate or uploadencoded content to a broadcast server using the first communicationchannel. In this example, the ACR fingerprinter 122 can communicate ACRfingerprinting information to the ACR cloud 110 using the secondcommunication channel. The first and second communication channels canbe wired or wireless communication channels, such as Wi-Fi communicationchannels or cellular communication channels.

In one example, where the capturer 114 splits the audio/video data fordelivery to the ACR fingerprinter 122 and the segment encoder 116. Inanother example, the content device 102 encodes and uploads the mediacontent using the segment encoder 116 and uploader 118 and ACRfingerprints the media content using the ACR fingerprinter 122 at thesame time or over a threshold period of time. In another example, thecontent device 102 encodes and uploads the media content using thesegment encoder 116 and uploader 118 in parallel with ACR fingerprintingthe media content using the ACR fingerprinter 122.

In one example, the capture interface 106 receives the media contentfrom the content feed 124 and delivers the media content to the capturer114. The capturer 114 can split the media content into multiple threadsor processes that can be processed by the segment encoder 116 and theACR fingerprinter 122 simultaneously or in parallel. In this example, afirst thread or process can be encoded by the segment encoder 116 anduploaded by the uploader 118. In one embodiment, a second thread orprocess can be fingerprinted by the ACR fingerprinter 122 simultaneouslyor in parallel with the encoding. In another embodiment, the capturer114 can deliver one or more threads or processes to different externalACR fingerprinters for fingerprinting.

The content device 102 can be a centralized device that can encode andfingerprint media content in parallel to provide media content withcontextually-relevant content to the media consumption device. Anadvantage of encoding and fingerprinting the media contentsimultaneously or in parallel at the content device 102 is to minimizean amount of infrastructure, overhead, and monitoring used. Anotheradvantage of the content device 102 encoding, uploading, andfingerprinting content can be to provide fault tolerant contentstreaming with ACR fingerprinting. For example, when the ACRfingerprinter 122 fails, content streaming can continue withoutinterruption and the ACR fingerprinting can be restarted. In oneexample, the fault tolerant content preparation system 100 can performACR fingerprinting as a separate process from content encoding anduploading to avoid faults in providing streaming content for viewing.

In one example, the ACR fingerprinter 122 can perform ACR fingerprintingupstream of broadcast distribution in the content preparation system100. In another example, the ACR fingerprinting can occur in thebroadcast chain where broadcast feeds can be delivered for encoding anduploading. An advantage of performing ACR fingerprinting where thebroadcast feeds can be delivered for encoding and uploading can be toenable the content preparation system 100 to combine the ACRfingerprinting, encoding, and uploading into a single device. Anotheradvantage of performing ACR fingerprinting where the broadcast feeds canbe delivered for encoding and uploading can be to utilize a singlebroadcast feed to perform ACR fingerprinting, encoding, and uploading.When a single broadcast feed is used, a number of devices and/orapplications to be purchased, installed, monitored, and maintained forACR fingerprinting, encoding, and uploading of content by an enterprisecan be reduced. For example, capital expenses (CAPEX) and/or operationalexpenses (OPEX) of the enterprise can be reduced, such as a reducedsystem infrastructure (rack space, power, and Ethernet connectivity).Additionally, when a single broadcast feed is used, a number ofbroadcast feeds generated from a broadcaster's distribution amplifiercan be reduced.

FIG. 2 illustrates a method 200 of the content device 102 (illustratedin FIG. 1) for encoding and automatic content recognition (ACR)fingerprinting according to one embodiment. The method 200 may be atleast partially performed by processing logic of the content device 102that may include hardware (e.g., circuitry, dedicated logic,programmable logic, microcode, etc.), software (e.g., instructionsexecuted by a processing device), firmware or a combination thereof. Theprocessing logic of the content device 102 can include the captureinterface 106, the capturer 114, the segment encoder 116, the uploader118, and one or more ACR fingerprinters 122.

Referring to FIG. 2, the method 200 begins with capturing media content,by capture interface 106, from the content feed 124 (210). The methodcan also include communicating, by the capture interface 106, the mediacontent to the capturer 114 (220). The method can include,communicating, by the capturer 114, the media content to the ACRfingerprinter 122 and to the segment encoder 116 (230).

The method can also include encoding, by the segment encoder 116, thecontent based on encoding criteria to obtain encoded content (240). Inone example, the encoding criteria can include: a security encryptionformat; display size adjustment information; network processingcapabilities information; network communication condition information;or battery capabilities of a media consumption device. In one example,the battery capabilities of media consumption device may bepredetermined and stored at the content device. In this example, thecontent device can encode the media content based on the batterycapabilities to reduce battery drain using lower resolution mediacontent for battery capacity limited media consumption devices orincrease the resolution of the media content when the battery capacityof the media consumption device is relatively large. The method can alsoinclude sending, by the segment encoder 116, the encoded content to theuploader 118 (250). The method can also include receiving, from thesegment encoder 116, the encoded content at the uploader 118 (260). Themethod can also include uploading, by the uploader 118, the encodedcontent to the broadcast server or cloud 112 (270).

The method can also include determining, by the ACR fingerprinter 122,the ACR fingerprinting information based on the media content (280). Themethod can also include communicating, by the ACR fingerprinter 122, theACR fingerprinting information to the ACR cloud 110 (290). In oneexample, the encoding the media content (240-270) and ACR fingerprintingof the media content (280-290) are done at the same time or in parallel.In another example, the encoding the media content (240-270) and ACRfingerprinting of the media content (280-290) are done independent ofeach other.
